Spectral Energy Distribution of Markarian 501: Quiescent State vs. Extreme Outburst
The VERITAS Collaboration, V. A. Acciari, T. Arlen +225
The very high energy (VHE; E > 100 GeV) blazar Markarian 501 has a well-studied history of extreme spectral variability and is an excellent laboratory for studying the physical pro…
Insights Into the High-Energy Gamma-ray Emission of Markarian 501 from Extensive Multifrequency Observations in the Fermi Era
LAT collaboration, A. A. Abdo et al., the MAGIC collaboration +6
We report on the gamma-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average LAT gamma-ray spectrum of Mrk 501 can be well descr…
Detection of very high energy gamma-ray emission from the Perseus cluster head-tail galaxy IC 310 by the MAGIC telescopes
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +151
We report on the detection with the MAGIC telescopes of very high energy gamma-rays from IC 310, a head-tail radio galaxy in the Perseus galaxy cluster, observed during the interva…
MAGIC Upper Limits for two Milagro-detected, Bright Fermi Sources in the Region of SNR G65.1+0.6
J. Aleksić, L. A. Antonelli, P. Antoranz +144
We report on the observation of the region around supernova remnant G65.1+0.6 with the stand-alone MAGIC-I telescope. This region hosts the two bright GeV gamma-ray sources 1FGL J1…
A study of high-energy proton induced damage in Cerium Fluoride in comparison with measurements in Lead Tungstate calorimeter crystals
G. Dissertori, P. Lecomte, D. Luckey +5
A Cerium Fluoride crystal produced during early R&D studies for calorimetry at the CERN Large Hadron Collider was exposed to a 24 GeV/c proton fluence Phi_p=(2.78 +- 0.20) x 10EE13…
Magic constraints on Gamma-ray emission from Cygnus X-3
J. Aleksić, L. A. Antonelli, P. Antoranz +156
Cygnus X-3 is a microquasar consisting of an accreting compact object orbiting around a Wolf-Rayet star. It has been detected at radio frequencies and up to high-energy gamma rays…
MAGIC observation of the GRB080430 afterglow
MAGIC Collaboration, J. Aleksić, H. Anderhub +151
Context: Gamma-ray bursts are cosmological sources emitting radiation from the gamma-rays to the radio band. Substantial observational efforts have been devoted to the study of gam…
Search for an extended VHE gamma-ray emission from Mrk 421 and Mrk 501 with the MAGIC Telescope
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +148
Context: Part of the very high energy -ray radiation coming from extragalactic sources is absorbed through the pair production process on the extragalactic background light phot…
Gamma-ray excess from a stacked sample of high- and intermediate-frequency peaked blazars observed with the MAGIC telescope
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +147
Between 2004 and 2009 a sample of 28 X-ray selected high- and intermediate-frequency peaked blazars with a X-ray flux larger than 2 uJy at 1 keV in the redshift range from 0.018 to…
MAGIC TeV Gamma-Ray Observations of Markarian 421 during Multiwavelength Campaigns in 2006
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +145
The Major Atmospheric Gamma Imaging Cerenkov (MAGIC) telescope participated in three multiwavelength (MWL) campaigns, observing the blazar Markarian (Mkn) 421 during the nights of…
